RISLONE® ENGINE OIL SUPPLEMENT with ZINC
TREATMENT 3X CONCENTRATED ZDDP
P/N 44405
What is Rislone Engine Oil Supplement with Zinc Treatment?
Rislone Engine Oil Supplement with Zinc Treatment is a petroleum oil performance supplement “booster”
containing high levels of ZDDP (zinc dialkyldithiophosphate) Zinc and Phosphorus additives to help better
protect internal engine components including pistons, flat tappet camshafts, lifters and the valvetrain. This
is especially important at engine start up, when most wear is done. That is why they say one of the worst
things you can do is start your engine.
What is ZDDP?
ZDDP, also called ZDP, is short for zinc dialkyldithiophosphate, is basically a combination of zinc and
phosphorus. When put under pressure, like between a flat tappet camshaft and a lifter, it attaches to the
metal surface and becomes a sacrificial wear material. Beyond being an anti-wear additive, it also is a
corrosion inhibitor.
Why do I need ZDDP?
Over the years motor oils have been updated to meet the needs of changing engine designs. In the past
the oil companies were able to do this and keep the engine oil backward compatible, meaning this engine
oil worked on new and old engines. However, now with the reduction of Zinc in the oil, these oils sold today
do not offer the protection needed for older engines.
How does Rislone Engine Oil Supplement with Zinc (ZDDP) Treatment work?
The common element between all of the engine components is the oil. Oil is the life-blood of the engine and
is pumped under pressure to the internal parts. Engine oils are generally used to reduce friction between
moving parts. In addition to lubricating, motor oil must cool, provide corrosion protection and a method of
removing contaminants. The main parts needing oil for lubrication is the valvetrain including the camshaft &
lifters, bearings and pistons. When installed, Rislone Engine Oil Supplement with Zinc Treatment cools and
lubricates these moving parts better then oil alone. The clinging properties hold the oil to metal parts
preventing wear and dry starts. Special additives also prevent oil thinning at high temperatures where
normal oil fails. The ZDDP creates the sacrificial (disposable) layer on any component where metal to
metal contact happens preventing the metal itself from being worn away.
What are the benefits of Rislone Engine Oil Supplement with Zinc Treatment over
other engine additives?
Some additives are designed for break-in use only. Other additives make wild claims about coating the
inside of the engine with Teflon type additives, but no real proof has been established to back up these
claims. Rislone Engine Oil Supplement with Zinc Treatment uses proven ZDDP technology along with our
90 plus years of oil additive knowledge to protect the moving parts of your engine to be used after break-in.

Can I use Rislone Engine Oil Supplement with Zinc Treatment in my newer vehicle?
No, you should not use Engine Oil Supplement with Zinc Treatment in 2005 and newer Petrol and 2007 and
newer diesel engines. Current oils have enough Zinc to protect moving parts inside newer engines.
However, to help prevent sludge and keep that engine clean, it is recommended to use Rislone Engine
Treatment p/n 44100.
How is Rislone Engine Oil Supplement with Zinc Treatment different than break in
additives?
Break in additives contain extremely high concentrations of ZDDP and are only designed to be left in the
engine for a short period of time. Many of these additives don’t contain detergents or other lubricity
additives important to keeping your engine clean and lubricated for thousands of kilometers. Rislone
Engine Oil Supplement with Zinc Treatment not only contains the correct amount of ZDDP, but also the
other additives important to protecting your engine. Do not use as a break in additive.
How can the Rislone Engine Oil Supplement with Zinc Treatment help prevent dry
starts?
Rislone Engine Oil Supplement with Zinc Treatment contains copolymer esters (Tackifier) that have an
affinity (attraction) for metal surfaces. This allows the oil to hold onto the metal surface instead of just
running off like normal motor oil does over time. This along with the ZDDP creates a double layer of
protection.
Will it work in synthetic oil?
Yes, Rislone works with all petroleum-based motor oils including conventional, high kilometer and synthetic
formulas.
How much Rislone Engine Oil Supplement with Zinc Treatment do I install?
(Do not overfill)
PETROL ENGINES (Cars & Light Trucks)
1996 and older – Add one bottle to engine crankcase.
1997 to 2004 – Add approximately ½ bottle (162 mL) to engine.
DIESEL ENGINES (Light, Medium & Heavy-Duty)
2006 and older – Add one bottle to engine crankcase for every 5 litres of oil capacity.
OTHER APPLICATIONS
For 4-stroke marine & motorcycles, agricultural, industrial and racing applications use 65 mL for every quart
of capacity.
When should I add to my engine?
For best protection, use Rislone Engine Oil Supplement with Zinc Treatment with every oil change. Also
can be used to top off oil as needed to improve engine protection between oil changes.
How long does Rislone Engine Oil Supplement with Zinc Treatment last?
When used in combination with good quality motor oil, Rislone Engine Oil Supplement with Zinc Treatment
will last until your next oil change. Follow the manufacturers recommended oil change intervals for your
particular vehicle and make sure to add with each oil change.
Can I use Rislone Engine Oil Supplement with Zinc Treatment in my diesel engine?
Yes, it is recommended to use at a 7% ratio for all 2006 and older diesel engines.
